FLOOD-GATE.

Application filed December 11, 1911.

Specification of Letters Patent.

Patented June 4, 1912. Serial No. 665,024.

To all whom it may concern:

Be it known that I, GEORGE S. GARDNER, a citizen of the United States, residing at Flemingsburg, in the county of Fleming, State of Kentucky, have invented certain new and useful Improvements in Flood- Gates; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to that type of devices known as fiood gates, and has for its object to produce a device of this character so constructed that the same will be held in normally perpendicular position, but will fold when the pressure of the water overcomes the springs.

WVith theseand other objects in view, the invention consists in certain novel features of construction, combination and arrangement of parts as will be hereinafter fully described and claimed.

In the drawings: Figure is a front elevation of the gate. Fig. 2 is a side elevation of the same.

Referring to the drawings, the numeral 1 designates a pair of spaced cement blocks which are embedded in the bed of the stream, each of which being provided with eye-bolts 2, the same being secured in the blocks 1 during the molding process.

A pair of metal posts 3 are provided, and have their lower ends formed with eyes 4 for pivotally engaging the eye-bolts 2. Connecting the posts 3 are bars 5, to which are secured the vertically disposed slats or panels 6.

The upper ends of the posts 3 project slightly above the upper bar 5 and are provided with slots 7, the purpose of which will appear later.

Positioned immediately in the rear of each block 1 is a block 8, said blocks being spaced a short distance from the blocks 1, and are also provided with eye-bolts '9. Pivotally connected to the eye-bolts 9 by eyes 10 are the lower ends of the rods 11, the upper ends of said rods passing through the slots 7 of the posts 3 and are threaded for the reception of nuts 12, which prevent said posts from becoming accidentally disengaged from the rods 11.

Surrounding the rods 11 are coil springs 13, the upper ends. of which bear against the upper ends of the posts 3, and the lower ends against the eye-bolts 9 in the blocks 8. Said springs acting to hold the gate in a normal perpendicular position, but allowing said gate to fold, as shown in dotted lines Fig. 2 of the drawing and during floods the pressure of waterovercomes the resistance of the springs.

From the foregoing it will be seen that the gate is exceedingly simple in construction and will yield under different pressures of water, and upon the pressure being relieved the gate will return to its normal position.

What is claimed is:

1. In a device of the class described the combination with a pair of blocks, posts pivotally connected to the blocks, a gate frame carried by the posts, a second pair of blocks arranged in the rear of the first named blocks, rods pivotally connected at their lower ends to the second named blocks and having their upper ends slidably connected to the posts, and means carried by said rods to hold the gate frame yieldably supported in a perpendicular position.

2. The combination with a pair of blocks having eye-bolts secured thereto, of a gate comprising side posts, the lower ends of which are pivotally connected to the eyebolts, slots formed in the upper ends of said posts, a second pair of blocks spaced from the first named blocks and having eye-bolts secured thereto, rods pivotally connected at their lower ends to said eye-bolts, the upper ends of the rods being slidably mounted in the slots of the posts, coil springs surrounding the rods and having their upper ends bearing against the posts and their lower ends against the eye-bolts of the second named blocks substantially as and for the purpose set forth.

In testimony whereof, I affix my signature, in presence of two witnesses.

GEORGE S. GARDNER.
